Efficient<i>N</i>-acylation of sulfonamides using cesium salt of Wells–Dawson heteropolyacid as catalyst: Synthesis of new<i>N</i>-acyl sulfonamides and cyclic imides
Abstract N-acylation of substituted sulfonamides with different anhydrides in the presence of Cesium salt of Wells–Dawson heteropolyacid (Cs5HP2W18O62) as an efficient and reusable catalyst was investigated for the first time. Cs5HP2W18O62 was used with a catalytic amount in water as a green solvent. At room temperature, a series of N-acylsulfonamides were synthesized, while under refluxing conditions
This invention relates to a solid substrate that has a modified surface to which a sulfoamido group is attached via a linker.

Disclosed is a method of producing replicates of sample nucleic acids. The method can include providing an insoluble support comprising attached oligonucleotides, annealing sample nucleic acids to the attached oligonucleotides; constructing template nucleic acids by extending the attached oligonucleotides using a polymerase; and transcribing the template nucleic acids to produce RNA replicates of the sample nucleic acids The attached oligonucleotides comprise a promoter sequence and a target annealing sequence, and (2) the proximal end of the promoter sequence is spaced from the insoluble support by a predetermined distance.

Disclosed is a substrate that includes a promoter primer that can be extended to form a transcribable template nucleic acid; and a capture probe. Typically, the promoter primer and the capture probe are non-complementary, and the capture probe can specifically bind to a target nucleic acid. The substrate can be used to amplify and detect one or more target nucleic acids.
